You didn't do something right. You were probably at TDC between the
exhaust and intake strokes when the adjustment was done. Here, both
vales will be slightly opened. Also, after you "properly" adjust the
lifters, you should wiat ~ an hour so they can bleed down a little to
let the valves close. Here is a procedure to help
1) Turn engine so it is at TDC, compression stroke for cylinder #1. This
is the right front cylinder. The ignition rotor should be pointing to
where the #1 spark plug wire is attached to the cap.
2) Adjust the valves, loosen the adjuster, then tighten to take up
slack, then tighten 1-2 additional full turns. It is normal to see the
valve raise or open. It will bleed down given time.
3) Turn engine 180 degrees (1/2 turn) counter clockwise. #2 (right rear)
should now be set for adjustment. Confirm ignition rotor now points to
where #2 spark plug wire is connected. Adjust as in step 2.
4) Turn engine another 180 degrees counter clockwise. Timing marks will
be back on top. #3 (Left Front) cylinder is now ready. Adjust as in step
2.
5) Turn engine 180 degrees counter clockwise. Cylinder #4 (Left Rear).
Adjust valves.
Replace valve covers, re-install distributor cap, and have a beer or cup
of coffee. Wait!
You should be good to go now.

Thanks for your replies all. Your responses confirm that I have been
indeed doing it right. So I'm a bit confused as to why if I set #1 at
TDC and set the valves, then when I go to do #2 why does #1 have a
significant amount of clearance again? Does this indicate a cam
problem? I guess I'm just getting frustrated becuase I've been tweaking
this about 5 or 6 times now to get it right and it just doesn't seem to
want to come together. The only time the car runs well and smooth is
backed off to .006", but it loud as hell (relatively). If I zero them
out (hot with the lifters pumped up), my car starts fine but begins to
run rough and make odd noises out the tailpipe after sitting a while.
If I turn them in past zero, the car will barely start and runs like
crap (but quiet as you could want). I know my lifters are bleeding off
too fast and getting squishy in a hurry. The car has 160000 miles on it
so I imagine the lifters could do with a replacement anyway, I'm just
also curious about the cam. I can live with the valves clearanced, but
I sure would like to have my car sound quiet like it should... BTW my
heads are new (yeah I should have changed the lifters then.. I know).
Also what's the P# for the collapsable pushrod tubes at BD, I see a
couple different ones each time I search?.
